Calcium Sulfite Balls Bath Tub Filter 99% Chlorine Removal Dechlorination Water Media
99% Chlorine Removal
Food Grade CaSO₃
Long Lifespan
Safe & Effective Water Treatment Media
Product Details
Engineered for Efficient Chlorine Removal
Designed with a high-porosity ceramic structure and premium calcium sulfite, these filter media deliver rapid reaction kinetics, high efficiency, and long-lasting performance in water treatment systems.
Chemical Reaction Mechanism
Calcium sulfite (CaSO₃) reacts with chlorine (Cl₂ / HOCl) in water through a reduction reaction, converting it into harmless substances.
Key Features:
Fast reaction speed (instant effect upon contact)
No electricity required
No secondary pollution

Vacuum package.
Vacuum Packaging for Guaranteed Performance Stability
To ensure that our calcium sulfite dechlorination ceramic balls maintain their chlorine removal efficiency and physical integrity during storage and transportation, we utilize industrial-grade vacuum packaging technology. This process effectively isolates the product from air and moisture, preventing any degradation in performance over time. 
Compared to traditional activated carbon for dechlorination, calcium sulfite ceramic balls offer advantages such as long-lasting, high efficient, safe, high-temperature resistance, and no bacterial growth.
In comparison with KDF copper-zinc alloy, it has a lower production cost and more effective in removing chlorine.
Chlorine Removal Test
Add a residual chlorine test reagent to both tap water and water soaked with dechlorination balls. If the water soaked with dechlorination balls does not turn yellow, it indicates that the dechlorination balls can effectively remove the residual chlorine from the water.
Blue ink test
Add blue ink reagent to both tap water and water soaked with dechlorination balls. If the water soaked with dechlorination balls does not turn blue, it indicates that the dechlorination balls can effectively remove industrial pollutants from the water.
